Viswa has taught extensively in fields ranging from operations research, computer science, software engineering, management information systems, and enterprise systems. In addition to teaching at the university, Viswa has conducted training programs for industry professionals. He has written several peer-reviewed research publications in journals such as Operations Research, IEEE Software, Computers and Industrial Engineering, and International Journal of Artificial Intelligence in Education. He has authored a book titled Data Analytics with R: A hands-on approach. Viswa thoroughly enjoys hands-on software development, and has single-handedly conceived, architected, developed, and deployed several web-based applications. Apart from his deep interest in technical fields such as data analytics, artificial intelligence, computer science, and software engineering, Viswa harbors a deep interest in education, with special emphasis on the roots of learning and methods to foster deeper learning. He has done research in this area and hopes to pursue the subject further. Viswa would like to express deep gratitude to professors Amitava Bagchi and Anup Sen, who were inspirational forces during his early research career. He is also grateful to several extremely intelligent colleagues, notable among them being Rajesh Venkatesh, Dan Richner, and Sriram Bala, who significantly shaped his thinking. His aunt, Analdavalli; his sister, Sankari; and his wife, Shanthi, taught him much about hard work, and even the little he has absorbed has helped him immensely. His sons, Nitin and Siddarth, have helped with numerous insightful comments on various topics.

    There are better options
    By Dimitri Shvorob
    Packt's Indian roots and willingness to publish anything, on one hand, and India's vast supply of English-speaking IT specialists, on the other hand, have been a dangerous combination: burned by several disasters in book form, I was opening "R Data Analysis Cookbook" with some trepidation. In the event, I was pleasantly surprised to discover a below-average-quality but decent book, which supplements familiar "standards", done by other books, with original material, e.g. when it discusses calling R from Java, or uses RgoogleMaps package. I would guess a 50/50 split of the page count between (a) machine-learning/"data science" methods and (b) "everything else", primarily data manipulation and visualization. My concern is that the latter is not sufficiently substantial to make up for the fact that on the former, "R Data Analysis Cookbook" is weak, whether viewed in isolation or compared against other titles. I would not recommend the purchase, and suggest "R in Action" by Kabacoff - a high-quality R introduction with a substantial statistics-and-machine-learning component - of the heftier and more expensive "R Book" by Crowley as superior alternatives.

    UPD. With the benefit of a little more life experience, I would say: don't spend your time on *any* R book. Python is the way to go.

    good R book with succinct code and clear explanations
    By DWR
    The R Data Analysis Cookbook offers succinct examples on a variety of data analysis topics including vectorized operations, using the apply / lapply / sapply family of functions, exploratory data analysis, classification, regression, data reduction techniques and geospatial analysis. I enjoyed the sections that dealt with using shiny and the various treatments of regression techniques. I thought the section that covered time series analysis was well done overall, and would have liked to have seen the authors expand upon that topic in more detail, though I understand that space must have been somewhat constrained given the number of topics this volume addresses.

    The book provides recipes relevant to start your data analysis side project using R.
    By Venkatesh-Prasad Ranganath
    Of the various books about R and data analysis, this one hits the road running. It is primarily focused on data analysis using R (in that order). To do so, it assumes that you know what you want to get done with data analysis and provides recipes to get you started with various tasks to do data analysis.

    That said, it does not provide information about R language features or explain how a specific analysis technique works. For such information, you will have to look elsewhere such as "Art of R Programming" and "Machine Learning: An Algorithmic Perspective".
